5. Operation Modes
Note:
1. Refer to 3. Operation Panel for details on using the operation panel and understanding the display meaning.
2. Each of the display diagrams shown in this chapter is for reference only. Actual display depends on the UPS operation.
5.1 Standby Mode
After the UPS is connected to the AC utility, it will supply power to the UPS and the batteries will be charged. The default
setting of the UPS is 'STANDBY mode'.
5.2 On-Line Mode
In on-line mode, the connected loads are supplied by the inverter, which derives its power from the utility AC power. The UPS
charges the batteries and provides power protection to its connected loads.
Note: Also includes Frequency Conversion.
5.3 Bypass Mode
In bypass mode, the critical loads are directly supplied by the utility power and the batteries are charged.
5.4 Economy Mode
Economy mode refers to an optional UPS configuration for reduced power consumption and heat output. A UPS in economy mode
reduces power consumption by suspending the double-conversion (AC-to-DC / DC-to-AC) process whenever input power is already
of high enough quality to pass through to connected equipment unchanged. The UPS will automatically switch back to on-line
mode if input power quality deteriorates to ensure connected equipment receives high-quality power under all conditions.
5.5 Battery Mode
When the UPS is operating during a power outage, the batteries' DC power is inverted to AC and continues to provide power to
the attached load(s) until a graceful shutdown can be completed.
Tripp Lite's PowerAlert
software is downloadable free of charge at www.tripplite.com/poweralert to monitor remaining battery
®
capacity before and during a power outage. An optional SNMP card may be used to monitor and control the UPS across a
network. Refer to www.tripplite.com/products/power-management-software-hardware~10 for more details on Tripp Lite's
SNMP management cards.
